tyre pressure alert

Shame it only monitors 4 tyres, not very good if towing :((

Cheers Kev

Check out the ones that Derek from ABR sells. Called the Jette 400, they can monitor up to 22 tyres simultaneously. They use the external monitor. This means you only need to buy enough monitors to cover the number of wheels you have "on the ground" at any one time.

For example, I have 8 wheels/tyres, but only 6 of them are ever on the road at any one time. So, instead of having 8 sensors in the 8 tyres, I only have 6. If I do get a flat tyre, or decide to rotate my wheels etc, I can keep the same sensor on the same position of the rig, so I don't have to re-program the damn monitor inside the cab.

The issues of the senders being stolen and/or knocked off can be covered too (to a certain extent).

To avoid them being stolen, they come with a lock-nut which threads onto the valve stem and can be held firmly in place with 3 very small Allen bolts. This would make them a PITA to remove (for airing up/down etc), so what will be doing at the next opportunity (when I get my tyres balanced etc), will be to get a second valve stem fitted. This will be one of those short solid stems they use on mag wheels etc and I will get in mounted more towards the inside of the rim and so that it doesn't protrude outwards.

That should help to alleviate the 2nd issue (of the units being accidently ripped off in rough terrain).

Hi Roachie.
I recently had a reply from Derek (see thread 49479) re the performance of the tyre monitor system.."My tyre pressure monitors worked 100% on the car but I had to fit 15mm metal valve extenders on the van as the valve stems are very short and the rim / van was creating interference and I was getting a sensor drop out every now and again."
Might pay to keep that in mind if you are going to locate the senders further into the rim. Also I beleived (and I may be wrong here ) that it is illegal to drill any further holes into the rims??

G'day Brenton and thanks for the thoughts.

With regard to the signal strength, I think the fact that the planned new valves would be fully metalic (as opposed to the standard rubber type), the signal strength should be okay. Given that the system is set to be able to monitor a tri-ax semi trailer (22 wheels), you would imagine that it should be able to pick-up the signalsfrom a close-by camper trailer or caravan.

Secondly, if they wanted to ping me for something like drilling another hole in my rims, it would be well down on the list of things they would be worried about (chief among them the 3500kg minimum weight of my Patrol)...... hahaha. However, I don't believe the drilling of a 2nd hole is illegal, as there are a number of blokes who fit those internal bead locks which require a separate air inlet via a hole drilled in the rim.

Currently testing these on my vehicle for the last two months Gates Wireless Tyre Monitors
Initial indications are impressive and will have report out on Pajero Club Public Forum next week.

Thank you all very much, you have given me much to work with.

I've had a Sensatyre kit for 3 years with no problem, they have 2 year warranty, why don't you contact the supplier.

ACDC,
I bought via the internet from a company over East, they wanted me to send the unit back to them so they could figure out what was going on. I took the valve sensor out of the tyre and in all honesty I never got around to sending it back to them. A second one developed a small air leak so that was two out of four, that was it for me, all be came to hard, I didn't want the problem when I was miles from anywhere. Took the safer option, I'm taking the rest out this weekend.
